To the trunk and rear wheel wells, reasonable improvement on road noise and general deadness
Now, I was thinking either second skin luxury liner pro on top of the tyre cover or actually on the rear trunk, not quite sure where is best but I'm guessing it may be a bit heavy for the tyre cover.
Which got me thinking, presumably, carpet is a pretty good barrier for sound, since the standard boot mat is thin as anything, what about lying some carpet underneath it? Seen mention that felt underlay is good, but which do you guys reckon is worth trying more? Bit of underlay underneath the z boot mat or thicker carpet? Or maybe even both...
Cheers
